Customization Process for New Relay Protection ODN Optical Distribution Network

Customization Process for New Relay Protection ODN Optical Distribution Network

This document provides guidance on optical distribution network (ODN) design for fiber-to-the-home (FTTH) deployments. It discusses ODN topology design including star, ring and bus configurations. This Technical Specification (TS) has been produced by ETSI Technical Committee Access, Terminals, Transmission and Multiplexing (ATTM). In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be interpreted as described. A centralized OTDR-based solution is the core of this evolved methodology, which greatly improves the visibility and operation efficiency in maintaining ODN quality and resilience. An Intelligent ODN fuses electronic labels/QR codes, high-dynamic-range smart OTDR, and a unified management platform (GIS + topology + data governance). An Optical Distribution Network (ODN) serves as the bridge in a Passive Optical Network (PON), transmitting optical signals from the Optical Line Terminal (OLT) to the Optical Network Unit or Terminal (ONU/ONT), thus linking a service provider's core network to end-users (residential or business).

New Vertical Cavity Surface Emitting Laser

New Vertical Cavity Surface Emitting Laser

The surface emission from a bulk semiconductor at ultra-low temperature and magnetic carrier confinement was reported by Ivars Melngailis in 1965. The first proposal of short VCSEL was done by Kenichi Iga of Tokyo Institute of Technology in 1977. Contrary to the conventional Fabry-Perot edge-emitting semiconductor lasers, his invention comprises a short laser cavity less than 1/10 of the edge-emitting lasers vertical to a wafer s. The ams OSRAM VCSEL (Vertical-cavity surface-emitting laser) technology includes the epitaxial structure and chip design, epitaxial growth, front- and back-end processing, packaging and advanced testing and simulations. The research project "Komplex-gekoppelte vertikal-emittierende Hybrid-Mikrokavitätslaser mit organischen, aktiven Halbleitermaterialien für den UV-Bereich" 1, which is funded by the Deutsche Forschungsgemeinschaft (DFG) is realizing laser-structures, that face the mentioned challenges.

New Lithuanian Fiber Optic Splice Box

New Lithuanian Fiber Optic Splice Box

The FIMP-M splice box, compactly sized at 115 x 61 x 113 mm, offers a versatile and efficient solution for fiber optic connectivity. Fiber optic laboratory testers provide accurate data on loss, performance, and signal quality, essential for developing, testing, and optimizing optical technologies. Their primary function is to protect and manage the spliced fiber optic cables, ensuring they remain secure, well-organised, and unaffected by environmental factors. We're excited to announce that ELPA REFURB will be exhibiting at ANGA COM 2026, taking place from 19–21 May 2026 in Cologne, Germany.
